Does California have daily overtime?
Yes. California has the most protective rules in the country: time and a half after 8 hours in a workday or 40 in a workweek, double time after 12 hours in a day, plus overtime for the first 8 hours of the seventh consecutive workday. That is on top of the federal baseline, so a California worker can earn overtime even in a week under 40 hours if a single day runs long.

The federal rule that always applies in California
Under the federal Fair Labor Standards Act (FLSA), covered non-exempt employees in California must be paid at least 1.5 times their regular rate for every hour worked over 40 in a workweek. The math is two steps: overtime rate = regular rate × 1.5, then overtime pay = overtime rate × overtime hours. The authoritative federal reference is the U.S. Department of Labor overtime page. Rules change — confirm anything time-sensitive with California's state labor department before relying on it.
No tax on overtime in California
Overtime has never had a special higher tax rate — it is ordinary income. And under the 2025 federal law commonly called “no tax on overtime,” eligible workers in California can deduct the premium portion of FLSA overtime (the extra 0.5x) from federal taxable income, up to annual caps, for tax years 2025 through 2028. Because it is federal, it applies in California the same as every other state. Estimate what it is worth with the no tax on overtime calculator.
